A new species of the genus <Emphasis Type="Italic">Chrysolina</Emphasis> Motsch. (Coleoptera,Chrysomelidae) from the mountains of Tuva and Buryatia

A new leaf-beetle species with two subspecies is described: Chrysolina (Pleurosticha) romani romani sp. et subsp. n. from southeastern Tuva and Ch. romani burjatica subsp. n. from the East Sayan in Buryatia. The habitus of the species is similar to both the representatives of the subgenus Arctolina Kont. and to Chrysolina gebleri L. Medv. from the subgenus Pleurosticha Motsch. The difference between these two closely related genera is discussed and causes to place the new species in the subgenus Pleurosticha, where it can be readily distinguished by the short and wide lentiform aedeagus.
